AHgen (Abstraction Hierarchy Generator) is an R package
to generate, analyse, compare, and visualise Abstraction Hierarchies.
AHgen was developed as part of the Water Resilient Cities
project (EPSRC EP/N030419/1), to compare Urban Systems Abstraction
Hierarchy (USAH) scenarios for UK cities using outputs from
OSMtidy. Its functions may be applied to analyse
Abstraction Hierarchies in any domain or at any scale.

The Abstraction Hierarchy is a method from the discipline of human
factors, as one part of the Cognitive Work Analysis framework (Jenkins, Stanton, and Walker (2009)). Originally
developed to improve the design of safety-critical work systems (e.g., a

systems at any scale – from microwaves to transport systems to entire
cities.
The Abstraction Hierarchy is a hierarchical network, wherein:
